The management of arrhythmias detected by implantable cardiac devices can be challenging. There are no formal international guidelines to inform decision-making. The purpose of this European Heart Rhythm Association (EHRA) survey was to assess the management of various clinical scenarios among members of the EHRA electrophysiology research network. There were 49 responses to the questionnaire. The survey responses were mainly (81%) from medium-high volume device implanting centres, performing more than 200 total device implants per year...

Using an implantable cardiac monitor (ICM) in patients with acute myocardial infarction (MI) allows continuous electrocardiogram monitoring and provides a much more detailed picture of the incidence of brady- and tachyarrhythmias than conventional follow-up. The CARISMA study was the first to use the ICM in post-MI patients with moderate to severe left ventricular systolic dysfunction. Atrial fibrillation (AF) events lasting longer than 30 s were associated with an almost threefold increase in the risk of major cardiac events...

INTRODUCTION: The implantable cardiac devices like regular pacemaker, cardiac resynchronization therapy (CRT) automatic implantable defibrillators (ICD) and CRT associate with ICD (CRTD) are now being used frequently. Patient visits to pacemaker and ICD clinics for review and monitoring, has increases significantly. We present the experience of monitoring via satellite of patients with implantable cardiac devices in Mexico. METHODS: Eighteen patients were selected from the arrhythmia Service Cardiac Electrophysiology and Stimulation of High Specialty Medical Unit (UMAE) of Specialties Hospital Dr...

AIMS: The remote monitoring of pacemakers and implantable cardioverter defibrillators (ICDs) promotes accurate supervision of the patient and device. Alert settings appear to be a crucial parameter of its efficacy. The purpose of our study was to evaluate various settings for alerts and alert message management in patients with pacemakers and ICDs. METHODS AND RESULTS: We prospectively evaluated 282 patients (181 males, 101 females, mean age 72 ± 11 years) who were referred to nine electrophysiological centres in the Veneto region of Italy for a pacemaker (76 patients) or ICD (206 patients) implant in which remote monitoring was activated (Biotronik Home Monitoring®, Biotronik, Berlin, Germany)...

The aim of this review is to summarize the available evidence on gender-related differences in outcome of invasive electrophysiological procedures. Gender exerts significant influences on the epidemiology, pathophysiology, and clinical presentation of many cardiac rhythm disorders. Women with supraventricular arrhythmias have a higher incidence of atrioventricular nodal reentrant tachycardia, a lower prevalence of atrioventricular accessory pathways, and increased arrhythmia inducibility during luteal phases of the menstrual cycle...

AIMS: Remote magnetic catheter navigation (RMN) may facilitate catheter ablation. However, as the system uses permanent magnets, interference (INF) with devices for pacing [pacemaker (PM)], defibrillation [implantable cardioverter defibrillators (ICD)], or cardiac resynchronisation [cardiac resynchronization therapy (CRT)] may occur. We investigated the effects of the RMN system on implanted arrhythmia devices in a prospective series. METHODS AND RESULTS: Prior to RMN-guided electrophysiological procedures, devices were fully interrogated and programmed to VVI 40/min with tachycardia detection off (if applicable)...

BACKGROUND: Disturbances in cardiac rhythm can lead to significant morbidity and mortality. Many arrhythmias are known to have a heritable component, but the degree to which genetic variation contributes to disease risk and morbidity is poorly understood. METHODS AND RESULTS: The EPGEN is a prospective single-center repository that archives DNA, RNA, and protein samples obtained at the time of an electrophysiologic evaluation or intervention. To identify genes and molecular variants that are associated with risk for arrhythmic phenotypes, EPGEN uses unbiased genomic screening; candidate gene analysis; and both unbiased and targeted transcript, protein, and metabolite profiling...

OBJECTIVES OF STUDY: Several studies have shown that heart failure may benefit from cardiac resynchronization therapy (CRT). Studies have demonstrated a beneficial effect of right ventricular (RV) bifocal pacing, using two leads at different positions, in similar patient populations. The aim was to evaluate this approach in Chagas disease patients who developed both severe dilated cardiomiopathy and chronic atrial fibrillation. METHODS: The study included 30 patients with a mean age of 52 +/- 6 years (16 male), who had atrioventricular block at functional class II or IV (NYHA)...

The challenge of preventing arrhythmic sudden death is one of the major issues of today's treatment of heart failure. To pursue this aim, an accurate selection of candidates for sudden death has to be routinely carried out, while a maximized and individualized drug treatment has to be extensively administered in all high-risk selected patients. However, in clinical practice there is no agreement on the selection criteria of sudden death risk, particularly in patients with advanced heart failure. Furthermore, the real impact of each category of drugs in reducing the risk of sudden death in heart failure patients is still under debate...
